Title: Speech recognition system having speech registration function based on two utterances of a word
Inventor: SHIMADA KEIKO
IPC: G10L15/06
Filed: 1990-11-09
Granted: 1996-01-23
Abstract: In a speech recognition system where a speech analyzer analyzes an input speech to produce an input speech pattern which is memorized in an input memory as a memorized input pattern, a pattern comparator comparing the memorized input pattern with reference patterns previously memorized in a reference pattern memory and producing pattern dissimilarities between them, and a speech deciding circuit  deciding  the  minimum  one  of  the  pattern dissimilarities to thereby recognize the input speech, a word is twice uttered to produce a first and a second speech during a registration mode in order to correctly register a speech pattern of the word into the reference pattern memory.   Speech patterns of the first and the second speeches are memorized into the reference pattern memory and the  input memory as a first and a  second memorized pattern, respectively, which are compared with each other at the pattern comparator to produce a pattern dissimilarity.     A  registration  deciding  circuit  is selectively coupled to the pattern comparator during the registration mode and decides whether or not the pattern dissimilarity is larger than a predetermined reject value and permits one of the first and the second memorized patterns to be registered as a reference pattern into the reference pattern memory when the pattern dissimilarity is not larger than the reject value.

Title: Network terminating terminal apparatus for integrated services digital network
Inventor: SPARKS THOMAS CHARLES
IPC: H04M11/06
Filed: 1991-11-08
Granted: 1999-07-20
Abstract: Network terminating terminal apparatus,  for use in an Integrated Services Digital Network, comprises a U-interface and a S/T interface.  The U-interface allows the integrated terminal apparatus to communicate with a central office directly, without a separate network terminator.  Remote terminals may be connected to  the  network  terminating  terminal  apparatus,  via  its  S/T interface.  The network terminating terminal apparatus serves then as a conventional network terminator.  The network terminating terminal apparatus includes circuitry for controlling D-channel access by the integrated terminal apparatus.  The circuitry detects the framing of the signal received at the U interface and the D-channel information from the remote terminals and ensures that the D-channel data from the integrated terminal apparatus is supplied to the S/T interface at the appropriate time for insertion into the D-echo channel of the signal returned to the remote terminals. In addition, the D-channel data from the integrated terminal apparatus is supplied to the U interface, with the D-channel from remote terminals,  for transmission in D-channel of the signal to the central office.

Abstract: A hematological specimen for classifying and counting leukocytes with a flow cytometer is prepared. A sample to be assayed is prepared by eliminating influences of erythrocytes from a hematological sample without changing leukocytes morphologically by adding a first aqueous solution of a low osmotic pressure comprising a buffer for adjusting the pH value within an acidic region and a second aqueous solution comprising an osmolarity compensating agent and a buffer for giving a pH value suitable for staining, optionally further adding a salt, which dissociates into ions in aqueous solutions so as to control the electrical conductivity of the aqueous solution at a preferable level, while damaging the cell membranes of erythroblasts contained in said sample; and staining the leukocytes with at least four dyes including Astrazon Yellow 3G and Neutral Red.      Thus leukocytes contained in the hematological sample can be classified at least eight groups two each comprising immature granulocytes, one comprising erythroblasts, one comprising basophils, one comprising eosinophils, one comprising lymphocytes, one comprising monocytes and one comprising-neutrophils, or nine groups involving one comprising blasts in addition to the above-mentioned eight groups, by assaying a single specimen with a flow cytometer.

Title: Impact pad with rising flow surface
Inventor: SOOFI MADJID
IPC: B22D11/116
Filed: 1992-08-21
Granted: 1998-05-05
Abstract: An improved impact pad includes a plurality of channels which direct the flow of molten iron or steel toward the tundish drains, and ramps which elevate the flow in the directions of the drains.  The ramps cause the molten iron or steel to follow a trajectory path after leaving the impact pad, first rising and then falling toward the drains.  The trajectory path increases the residence time of the molten iron or steel in the tundish, allowing more time for impurities to float to the top of the vessel.  The trajectory path also helps propel the impurities partially toward the top of the tundish vessel.

Title: Method and machining apparatus for use especially in the sanding of items of wood in a sanding machine
Inventor: HUNDEBOL KELD OTTING
IPC: B24B41/047
Filed: 1991-05-21
Granted: 2002-04-23
Abstract: In order to be able to sand the surface of an item (3) uniformly smooth, a sanding machine is used with sanding tools in the form of sanding rollers (29) which are rotated as well as turned in the same plane, and which at the same time herewith are also moved in a reciprocating manner transversely to and parallel with the direction in which the item is conveyed, whereby during the working stroke the sanding ele-ments on the sanding rollers (29) will sand at all pos-sible contact angles in relation to the item (3). The risk of sanding damage such as marks and grooves as a result of over-sanding, or the possible lack of sand-ing as a result of too sporadic contact, is herewith re-duced, and the best possible result is achieved. Fur-thermore, the wear on the sanding rollers (29) is com-pletely uniform, whereby their endurance is extended.     For the movement of the sanding rollers (29), there is used an apparatus comprising a motor-driven crank arm (7) which, in sliding engagement with a carriage which supports the sanding rollers (29), can drive the carriage forwards and backwards on rails (4) which extend transversely to the machine (1). There is here-by achieved a stable and robust construction which also gives the sanding rollers (29) an expedient move-ment characteristic, which compensates for the pre-dominantly longitudinal sanding movements to which the items are exposed in the outer areas.

Abstract: Apparatus for the physical vapour deposition of an alloy whose constituent elements have widely differing vapour pres-sures comprises an inner evaporation crucible (1) surrounded by a second evaporation crucible (2) having an array of nozzles (9) angled towards collector (5). In use of the apparatus, a charge (3) of relatively low volatility is evaporated from inner crucible (1) using an electron beam (7) focussed by magnet (8). Charge (4) in second crucible (2) is of much higher volatility and is evaporated by radiant heating. The nozzles (9) direct the vapour from charge (4) along pathways which intersect the vapour rising from charge (3) such that the combined vapour stream reaching collector (5) is an intimate mixture of constituents. The nozzles (9) may also serve to control the flow rate of vapour from the second crucible (2).
